I have a MacBook Pro A1502, the wifi icon dosen´t show up, I´ve changed the wifi card and still the same. the Bluetooth is also damage. When I change the card for another one the bluetooth appear, but the Wi-Fi still disable, I can´t start nor create the service throught the terminal, it says that there is no Wi-Fi device. HELP PLEASE!!! I also try to enable the wifi network service in the terminal but the listallnetworkservices command doesn´t show any wifi interface
I’m suspecting the I/O cable needs to be replaced. Here’s the IFIXIT guide for the 2014 model: MacBook Pro 13" Retina Display Mid 2014 I/O Board Replacement and here’s the needed part: MacBook Pro 13" Retina (Late 2013-Early 2015) I/O Board Data Cable but without knowing your exact system I’m just guessing here.
